PULLEY.

Specification of Letters Patent Patented Dec. 19, 1905.

Application filed April 2'7, 1905- Serial No. 257,754.

T0 (1.7 whom, it may concern:

Be it known that I, OTTO R.'Bnck, a citizen of the United States of America, and a resident of Quilcene, in the county of Jefferson and State of \Vashington, have invented certain new and useful Improvements in Pulleys, of which the following is a specification.

My invention relates to certain new and useful improvements in pulleys; and the primary object thereof is to produce a construction which possesses but few parts, is comparatively inexpensive to manufacture, and is efficient in operation.

A further object resides in the construction of the blocks side walls or chuck-plates.

With the above and other objects in view, as set forth in the following description, the invention consists of the parts, arrangement, and combination of parts hereinafter referred to and succinctly defined in the appended claims.

In the accompanying drawings,in which like numerals of reference indicate like parts throughout the several views, Figure l is a view in side elevation of the present invention. Fig. 2 is an end view thereof, and Fig. 3 is a diagrammatical view showing an application of my improvement.

The pulley-block comprises the cheek-plates or sides 1, which are rigidly connected together at their lower portions, and on a pintle 2, journaled in said cheek-plates, I mount for rotation the sheave 3. This sheave fits snugly between the cheek-plates, and at a point directly above this sheave 3 said cheek-plates are flared outwardly and upwardly, thereby providing convex surfaces 4:, which serve to guide the line or rope onto the sheave. Straps 5 are preferably formed integral with the outer faces of said cheek-plates, and one of these straps has pivoted in its upper end the cross-head or catch 6. The free end of this cross-head or catch is formed with an eye and is adapted to be received in a keeper formed by eyes or loops 7 on the upper end of the other strap, and a pin, as 8, is adapted to pass through eyes 7 and the eye of catch 6, thereby locking said catch in closed position.

My improvementis particularly adapted for use in connection with the hauling of logs, and in Fig. 3 an application thereof is shown. In this view a log 9 is illustrated as being drawn in, the same being connected by a hook 10 to the main line 11, which, as in the usual practice, is formed in sections connected at suitable points by swivels, one of which is indicated by reference-numeral 12. Referencenumeral 13 indicates the haul-back for returning the main line after the log has been conveyed to its destination, and this haul-back and the main line both pass through the throat 14 of the pulley-block until the log is drawn in proximity to the pulley. The cable directly attached to the log is then disconnected from hook 10, removed from the block, and then again connected to the hook, as indicated by the dotted line in Fig. 3. The side portions of the cheek-plates of the block are also flared, as at 15, and therefore all swivels and hooks in the main line will readily pass through the said throat 14 in an uninterrupted manner. The ropes or lines can be readily inserted in position in the block by unfastening the catch or cross-head 6.

I preferably cast the pulley-block so as to form an integral structure. This, however, is not absolutely essential, and, further, the details of construction can be readily varied without departing from the spirit of my invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States of America, is

1. A pulley comprising a block having opposite cheek-plates, and a sheave mounted for rotation between said plates, said plates having their upper portions flared outwardly from said sheave to form a wide throat, and the side portions of said cheek-plates at the opposite ends of said throat being flared.

2. Apulleycomprisingablockhavingopposite cheek-plates, and a sheave mounted for rotation between said plates, the side portions of said plates being flared to provide enlarged end portions to the throat of said block.

3. A pulley comprisinga block, and a sheave mounted for rotation therein, said block being provided with a throat whose end portions are flared outwardly.

Signed at Quilcene, \Vashington, this 15th day of April, 1905.
